Relationship between redshift and fractional contribution of AGN MIR emission for ULIRGs and LIRGs from the ADF–S sample. Filled red squares represent ULIRGs, while filled blue triangles represent LIRGs. The radii of circles correspond to the log(SFR) values for each galaxy (we used this as a scaling factor), that is, the larger the circle, the higher the measured SFR of the galaxy.
